Well, this is my first time making a tutorial, so I hope it's clear enough! I wanted to keep it simple...

This is the process I use for pictures such as [link] and [link]. For most of my pictures, I keep the flat colours on separate layers as it helps me focus on blending and detailing without making a mess. Hower, taking such measures for pictures which don't require a lot of attention is sometimes unnecessary! Learning this technique has been very useful to me as and it'd be great if other people find it useful too!

Awesome tutorial... this may seem a little unrelated to what you're trying to accomplish... but... what's the name of the font you used for the instructions? If you can let me know that would be great!
